Hello..
Im trying to make a connection between PC and PIC as you get from the topic..
In Hyperterminal; my pic can send a char. There is no problem. But when receiving any data, my pic doesnt break his silence. And this frustrates me..
As i search on net (and go into my electronic knowledge), i find that i should make common ground (pin 5). But when i try this; my pic doesnt send any char. (and nor recieves any data / char)When i leave this pin (5) float, it can send char. (dont say my pic is a little ... you get it)(and it cant receive). I think maybe i have problems in software. But it works well in Proteus / ISIS.
Any idea will be great help..
Sincerely..

maybe it helps;
im measuring 0 Volts on Pic's Receieve pin..
ive changed ihn232 with another but it stands like this.
im using 5 1uF caps..
ive tried both shorted RTS CTS - DTR DSR pins and not shorted.. only 2 pins connected ( RD TD )
it didnt help..
im using hyperterminal in handshaking none mode..
im thinking of a problem in software but it works in proteus..
maybe hardware
aarghh.. ive not much time.
(a circuit schematic will be nice but my draws are a mess..)
